Visual Basic Online Course - Create FTP

Visual Basic Online Course - Create FTP Client

VB6 Ftp Client
VB6 Ftp Client


In this project we shall discuss using Microsoft Internet Transfer Control or (INET.Ocx) to :
  1. Connect to FTP remote server.
  2. Retrieving main/sub directories from FTP remote server.
  3. Retrieving files from FTP remote server.
  4. Uploading file to FTP remote server.
  5. Downloading file from FTP remote server.
  6. Make new directory (folder) at FTP remote server.
  7. Rename & Delete file from FTP remote server.

In this project we won't be using API calls (i.e. INET API) also we will cover these issues :
    1. The Spaces problem while downloading and uploading files.
    2. Error message "Still executing last request" number 35764.
    3. Error message "File exists"
    4. Application Hangs up after ending it.
    5. Using TreeView control to list all the Directories on the FTP remote server.
    6. Using ListBox control to list all files on the FTP remote server related to above folder.


  • The project source code is uploaded to Mediafire.com direct link and no password.


  • The project exe file tested and debugged uploaded to Mediafire.com direct link and no password.


  • I will demonstrate a brief explanation now on how does it work and how did i code it to make things easy to follow the logic.

    MS Access 2003 Database Structure

    These are 2 methods on how to work with MS-Access 2003 Database components directly like (Tables & Queries) without opening your Data-Base file using ADO 2.8 .
    1) Using OpenSchema
    - Create new MS-Access 2003 DB (MyDb.mdb)
    - Create VB6 Project
    - Database (Fname Text 50,Lname Text 50, Nphone Text 50, Xemail Text 50)
    - Place both in the same directory of course.
    - Open your VB6 Project, from menu choose
    (Project, References, Microsoft Ado 2.8 and Microsoft ADOx)

    Visual Basic Online Course - Auto translate your application's Language before compiling

      Visual Basic Online Course

    Auto translate your application's language

     Using Conditional Compilation

    Conditional compilation lets you selectively compile certain parts of the program. You can include specific features of your program in different versions, such as designing an application to run on different platforms, or changing the date and currency display filters for an application distributed in several different languages.

    Structuring Code for Conditional Compiling

    To conditionally compile a part of your code, enclose it between #If...Then and #EndIf statements, using a Boolean constant as the branching test. To include this code segment in compiled code, set the value of the constant to –1 (True).
    For example, to create French language and German language versions of the same application from the same source code, embed platform-specific code segments in #If...Then statements using the predefined constants conFrenchVersion and conGermanVersion.
    #If conFrenchVersion Then
       ' .
    #ElseIf conGermanVersion then
       ' .
    #Else
       ' .
    #End If
    

    If the value of the conFrenchVersion constant is set to True at compile time, the conditional code for the French language version will be compiled. If the value of the conGermanVersion constant is set to True, the compiler uses the German language version.

    Declaring Conditional Compilation Constants


    There are three ways to set conditional compilation constants: in the Conditional Compilation Arguments field of the Make tab on the Project Properties dialog box, on a command line, or in code.

    Conditional compilation constants have a special scope and cannot be accessed from standard code. How you set a conditional compilation constant may depend on the scope you want the constant to have.
    How Set Scope
    Project Properties dialog box Public to all modules in the project
    Command line Public to all modules in the project
    #Const statement in code Private to the module in which they are declared


    Setting Constants on the Project Properties Dialog Box

    Before creating the executable file, from the Project menu, choose Project Properties, click the Make tab on the Project Properties dialog box, and enter an argument, such as conFrenchVersion = –1, in the Conditional Compilation Arguments field (if you are compiling your application for the French language version). When you compile the program, this argument will satisfy the #If...Then condition, and the code between the #If...Then and #EndIf statements will be included in the compiled program.
    If you have a complex #If...Then statement, containing one or more #ElseIf statements, you will need to set additional constants. You can set multiple constants by separating them with colons, as in the following example:
    conFrenchVersion=-1:conANSI=0
    

    Setting Constants on the Command Line

    If you want to start compilation from a command line, use the /d switch to enter conditional compilation constants, as shown here:
    vb6.exe /make MyProj.vbp /d conFrenchVersion=–1:conANSI=0
    No space is required between the /d switch and the first constant. Command-line declarations override declarations entered on the Project Properties dialog box, but do not erase them; arguments set on the Project Properties dialog box remain in effect for subsequent compilations.
    For More Information   See "#If…Then…#Else Directive" and "#Const Statement."

    I posted it here in case (Microsoft) stopped supporting, which will happen any time.
